> R is flexible when it comes to integer vs. floating point, generally
> obscuring the details inside a "numeric" class, but it knows how to make it
> seem like my integer-looking data stored in a double is actually integer.
> This means that an R user can think they have integers even when the
> underlying storage is not.
> So I would have expected this to work, and indeed to be one reason I'd want
> to specify a schema when creating a table:
> {code:r}
> > table(a = 1, schema = schema(a = int32()))
> Error in Table__from_dots(dots, schema) :
> Invalid: Cannot convert R vector of type REALSXP to integer Arrow array
> {code}
